Figure 4: Vent Connection to Inducer
A self-tapping sheet metal screw and high temperature sealant such as Dow Corning 736 or General Electric RTV106 (temperature rating 480°F minimum) should be used to secure both the flue pipe (MHA1/MDA1-50), and the Thermo Products supplied 4 in. adapter (MHA1/MDA1-75, MHA1/MDA1-100, MHA1/MDA1-125) to the outlet of the inducer. If using other than a self-tapping sheet metal screw to secure the flue pipe to the inducer, a starter hole must be drilled in the inducer before inserting the screw (refer to Figure 4) to avoid damage to the inducer housing.
